Abstract

Based on the theory of Winkler beam on elastic foundation, mechanical model of syncline genesis was established and deflections, bending moment and strain energy were deduced. Meanwhile, stress and energy conditions mining in syncline structure were analyzed from the point of formation mechanism of syncline structure using ground pressure theory and UDEC numerical simulation method. The results show that the formation of syncline is influenced by multiple factors. The larger the buried depth of coal seam, bulk density of overlying strata, characteristic coefficient and tectonic stress, the smaller foundation coefficient, and the easier syncline structure can be formed. Meanwhile, the closer the distance of working face to synclinal axis, the larger the ratio between shear and vertical stress and the surplus energy at the peak of abutment pressure in front of coal wall, and the greater the occurrence possibility of rock burst.
